In a three-node OpenStack architecture, the network node consists of services from which of the following OpenStack components? (Select the best answer.)
- Glance
- Horizon
- Keystone
- Neutron
- Nova
In a three-node OpenStack architecture, the network node consists of services from the Neutron component. OpenStack is an open-source cloud-computing platform. Each OpenStack modular component is responsible for a particular function, and each component has a code name. The following list contains several of the most popular OpenStack components:
-Nova -OpenStack Compute: manages pools of computer resources
-Neutron -OpenStack Networking: manages networking and addressing
-Cinder -OpenStack Block Storage: manages blocklevel storage devices
-Glance -OpenStack Image: manages disk and server images
-Swift -OpenStack Object Storage: manages redundant storage systems
-Keystone -OpenStack Identity: is responsible for authentication
-Horizon -OpenStack Dashboard: provides a graphical user interface (GUI)
-Ceilometer -OpenStackTelemetry: provides counterbased tracking that can be used for customer usage billing
A three-node OpenStack architecture consists of the network node, the controller node, and the compute node. The network node consists of the following Neutron services:
-Neutron Modular Layer 2 (ML2) PlugIn
-Neutron Layer 2 Agent
-Neutron Layer 3 Agent
-Neutron Dynamic Host Configuration Protocol (DHCP) Agent
The controller node consists of the following services:
-Keystone
-Glance
-Nova Management
-Neutron Server
-Neutron ML2 Plug-In
-Horizon
-Cinder
-Swift
-Ceilometer Core
The compute node consists of the following services:
-Nova Hypervisor
-Kernel-based Virtual Machine (KVM) or Quick Emulator (QEMU)
-Neutron ML2 Plug-In
-Neutron Layer 2 Agent
-Ceilometer Agent
